From 295640e6f4aa83b843e245bb1af9995be37de84d Mon Sep 17 00:00:00 2001 From: zhangjixiang <jixiang_zh...@h3c.com> Date: Sun, 25 Feb 2018 09:47:51 +0800 Subject: [PATCH] HMP: Initialize err before using
When bdrv_snapshot_delete return fail, the errp will not be assigned a valid value in error_propagate as errp didn't be initialized in hmp_delvm, then error_reportf_err will use an uninitialized value(call by hmp_delvm), and qemu crash.
